Description

Technical Field

[0001] This application relates to the field of electrical technology, and more specifically, to a display component and a household appliance. Background Technology

[0002] The display assembly includes a display panel and a display cover over the display panel. The display panel is equipped with ambient lighting and indicator lights. The ambient lighting can be controlled to form a halo effect for decorative purposes. The indicator lights can be controlled to display information such as weather, time, text, and images.

[0041] The technical solutions in the embodiments (or "implementations") of this application will now be clearly and completely described with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0042] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0043] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram illustrating the structure of a display component 1 mounted on an external mounting 2, as shown in an exemplary embodiment. Figure 2 An exploded view of the structure of display component 1 as shown in an exemplary embodiment. Figure 3 This is a schematic diagram of the structure of a display panel 11 as shown in an exemplary embodiment. Figure 4 This is a schematic diagram of the structure of the display cover 12 as an exemplary embodiment. Figure 5 yes Figure 1 A partial structural cross-sectional view along direction AA.

[0044] like Figure 1 and Figure 2 As shown, display assembly 1 includes a display panel 11, a display cover 12, and a light guide 13. Figure 3 As shown, the display panel 11 is equipped with an ambient light 111. When the display component 1 is in operation, the ambient light 111 can emit light of a specific color to create a specific environmental atmosphere.

[0045] like Figure 2 , Figure 4 and Figure 5 As shown, the display cover 12 is spaced apart on one side of the display panel 11. The display cover 12 has a light-reflecting area 122 for reflecting the light emitted by the ambient light 111. Specifically, the display cover 12 is opposite to the side of the display panel 11 where the ambient light 111 is located, and the light-reflecting area 122 of the display cover 12 faces the ambient light 111. When the ambient light 111 emits ambient light, the ambient light can reach the light-reflecting area 122 of the display cover 12 along the incident path λ1, and form reflected light after reflection.

[0046] Please continue to refer to Figure 2 and Figure 5 A light guide 13 is disposed between the display panel 11 and the display cover 12. The light guide 13 includes a light-diffusing section 131 disposed towards the outside of the display assembly 1, and the light-diffusing section 131 is located on the light reflection path λ2. The light guide 13 is configured to guide reflected light from between the display cover 12 and the display panel 11, through the light-diffusing section 131, to be uniformly emitted to the outside of the display assembly 1. Exemplarily, the light-diffusing section 131 can be made into a transparent rough structure, through which reflected light can be diffusely reflected in all directions to achieve a light-diffusing effect. Of course, the structure of the light-diffusing section 131 is not limited to this; for example, special scattering particles can be added inside the light-diffusing section 131 to scatter the reflected light multiple times to achieve a light-diffusing effect.

[0047] This application provides a light reflection area 122 on the display cover 12, which can reflect the light emitted by the ambient light 111. Then, the light reflected by the display cover 12 can be evenly emitted from between the display cover 12 and the display panel 11 to the outside of the display component 1 through the light doubling section 131. This can create an atmospheric effect in the surrounding area outside the display component 1, highlighting the display component 1 in space and increasing the sense of three-dimensionality and layering.

[0048] The light-reflecting area 122 can be set to be opaque to prevent the light emitted by the ambient light 111 from passing through the display cover 12. For example, the display cover 12 can be injection molded using an in-mold injection molding process, and then the light-emitting area of ​​the display cover 12 can be planned, and a light-shielding layer or a light-shielding film can be applied to the light-emitting area, but it is not limited to this.

[0049] In one embodiment, see Figure 5 and Figure 6 , Figure 6 This is a schematic diagram of the structure of the light guide 13 as shown in an exemplary embodiment.

[0050] The light guide 13 includes a first mounting portion 132 and a second mounting portion 133 spaced apart. The first mounting portion 132 is used to mount the display cover 12, and the second mounting portion 133 is used to mount the display assembly 1 to the external mounting object 2. The light-diffusing portion 131 is located between the first mounting portion 132 and the second mounting portion 133 and is configured to face the external mounting object 2. Thus, the light-diffusing portion 131 can uniformly project reflected light onto the external mounting object 2, forming a uniform halo effect on the external mounting object 2. The external mounting object 2 is not specifically limited here; for example, it can be the side wall or door of a household appliance, or a mounting plate on other electrical equipment.

[0051] It should be noted that the light guide 13, except for the light uniform part 131, can be integrally formed with the light uniform part 131.

[0052] Please see Figure 4 and Figure 5 In one embodiment, the display cover 12 includes a cover body 120 and a flange 121 extending inwardly from the cover body 120. The cover body 120 has a light-reflecting area 122. The first mounting portion 132 includes an edge mounting surface 1321 that mates with the flange 121. One end of the light-diffusing portion 131 is connected to the edge mounting surface 1321, and the other end of the light-diffusing portion 131 extends inwardly at an angle away from the cover body 120 and is connected to the second mounting portion 133. Thus, the light guide 13 is prevented from being exposed beyond the flange 121 to the outside of the display assembly 1, and the light reflection path between the light-diffusing portion 131 and the light-reflecting area 122 is shortened, achieving both aesthetics and light-diffusing effect.

[0053] For example, after the display cover 12 and the light guide 13 are pre-positioned, they can be welded together by laser welding at each mounting point. Of course, the connection method between the display cover 12 and the light guide 13 is not limited to this.

[0054] Please continue reading. Figure 5In one embodiment, the first mounting portion 132 further includes a body mounting surface 1322 that mates with the cover body 120; the second mounting portion 133 includes a mating surface 1331 for mating with the external mounting object 2. The mating surface 1331 is parallel to the body mounting surface 1322 and connected to the light-diffusing portion 131. The plane containing the light-diffusing portion 131 and the mating surface 1331 has an inclination angle α, which is an acute angle. After the display assembly 1 is installed on the external mounting object 2, the external mounting object 2 and the cover body 120 of the display cover 12 tend to be parallel. By determining the degree of inclination of the light-diffusing portion 131 relative to the mating surface 1331, the reflected light can be emitted perpendicularly as much as possible when passing through the light-diffusing surface, so as to reduce the refraction of light during the light-diffusing process and ensure that a uniform light ring can be formed on the external mounting object 2 after a certain distance.

[0055] Please continue reading. Figure 6 In one embodiment, the light guide 13 further includes a mating surface 134 for mounting the display panel 11, the mating surface 134 being parallel to the body mounting surface 1322. This allows for a flatter and more compact structure for the display assembly 1. Specifically, as... Figure 3 and Figure 6 After the side of the display panel 11 with the ambient light 111 is tightly bonded to the mating surface 134, it is secured using fasteners such as screws. In some embodiments, to make the connection between the display panel 11 and the mating surface 134 more stable, it can first be fixed by welding with hot melt pillars, and then four screws can be added at the four corners of the display panel 11 for secondary fixation. Of course, the connection method between the display panel 11 and the mating surface 134 is not limited to this.

[0056] Please see Figure 5 and Figure 6 In one embodiment, the mating surface 134 and the mating surface 1331 of the second mounting portion 133 are coplanar. The ambient light 111 protrudes from the display panel 11 by a height of b, the distance between the cover body 120 and the display panel 11 is h, and the distance between the flange portion 121 and the orthographic projection of the ambient light 111 on the cover body 120 is L. The above parameters and the tilt angle α satisfy the following relationship: L < (2h - 2b) / tanα. Thus, it can be ensured as much as possible that the halo effect formed by the reflected light after reaching the external mounting object 2 is not blocked by the display cover 12. In other words, the halo area formed by the ambient light 111 on the external mounting object 2 can be located outside the horizontal projection formed by the display cover 12 on the external mounting object 2.

[0057] Specifically, after the ambient light 111 emits light, it travels along the incident path λ1 to the light reflection area 122, and then reflects along the reflection path λ2 to the external mounting 2. According to the principle of light reflection, we can let the distance between the ambient light 111 and the normal v be x, and the distance between the position of the reflected light reaching the external mounting 2 and the normal be x. To ensure that the reflected light is not blocked by the display cover 12 after reaching the external mounting 2, we need to make 2x > L, and tanα ≈ (hb) / x. Therefore, we can obtain the relationship L < (2h-2b) / tanα.

[0058] Please see Figure 2 and Figure 6 In one embodiment, the display assembly 1 further includes a display back cover 16. The light guide 13 also includes a connecting portion 135 for mounting the display back cover 16. The mating surface 1331 and the contact surface 134 of the second mounting portion 133 are located on opposite sides of the connecting portion 135, respectively. Thus, the structure of the light guide 13 can be reasonably utilized to assemble the various components in the display assembly 1, making the overall structure of the display assembly 1 more compact.

[0059] It should be noted that one of the connecting part 135 and the display back cover may include a snap-fit ​​connector and the other may include a snap-fit ​​groove. The snap-fit ​​connector and the snap-fit ​​groove are used to fix the display back cover onto the light guide 13.

[0060] Please see Figure 3 and Figure 4 In one embodiment, the display panel 11 includes a peripheral region 114 and a central region 113 located inside the peripheral region 114. The display panel 11 also includes an indicator light 112 disposed in the central region 113; an ambient light 111 is disposed in the peripheral region 114. The display cover 12 further includes a light-transmitting region 123 located inside the light-reflecting region 122, for allowing light emitted from the indicator light 112 to pass through. Thus, the display information formed by the indicator light 112 can be seen in the central region 113 of the display cover, and the ambient light effect formed by the ambient light 111 can be seen around the outer perimeter of the display cover.

[0061] The peripheral region 114 and the central region 113 of the display panel 11 are relative terms. The peripheral region 114 is closer to the perimeter of the display panel 11 than the central region 113, while the central region 113 is farther away from the perimeter of the display panel 11 than the peripheral region 114.

[0062] Please continue reading. Figure 3In one embodiment, the display light 112 includes multiple display LEDs located in the central region 113, arranged in a matrix. The ambient light 111 includes multiple ambient LEDs surrounding the display LEDs. The multiple display LEDs, in different arrangements, can display various information such as weather, time, text, or images. The ambient LEDs can be arranged arbitrarily at the corners of the display panel 11. Compared to using traditional light strips, this reduces the blank areas at the corners of the display panel 11, resulting in a more seamless lighting effect at the corners.

[0063] Please see Figure 2 , Figure 3 , Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of a display bracket 14 as shown in an exemplary embodiment. Figure 8 This is a schematic diagram illustrating the structure of the display bracket 14 and the display panel 11 in cooperation with an exemplary embodiment.

[0064] In one embodiment, the display assembly 1 further includes a display bracket 14 disposed between the display cover 12 and the display panel 11, for supporting the display panel 11. The display bracket 14 is configured to cover the central region 113 and expose the peripheral region 114; the display lamp 112 includes a plurality of display lamp beads; the portion of the display bracket 14 covering the central region 113 has a plurality of cutouts 141 through which the plurality of display lamp beads pass. This avoids mutual interference among the individual display lamp beads during light transmission, preventing blurry display information on the display casing.

[0065] For example, the shape of the cutout portion 141 can be a symmetrical structure such as a square, rectangle, or circle, or other asymmetrical structures.

[0066] Please continue reading. Figure 8 In one embodiment, the distance d between the four edges of the display bracket 14 and the ambient lights 111 near each edge is equal. This avoids affecting the uniformity of the light emitted by the ambient lights 111 due to unequal distances between the ambient lights 111 and the edges of the display bracket 14.

[0067] Furthermore, in other embodiments, the distance between the four edges of the display bracket 14 and the edges of the display panel 11 that are on the same side and opposite to each other is also equal everywhere.

[0068] Please see Figure 9 and Figure 10 , Figure 9 This is a schematic diagram illustrating the structure of the anti-crosslight film 15 and the display bracket 14 in cooperation, as shown in an exemplary embodiment. Figure 10 This is a schematic diagram illustrating the structure of the anti-crosslight film 15, the display bracket 14, and the display panel 11 in cooperation with an exemplary embodiment.

[0069] In one embodiment, the display assembly 1 further includes an anti-crosslight film 15 affixed to the cutout portion 141, the anti-crosslight film 15 being located on the side of the display bracket 14 facing away from the display lamps 112. This further reduces the risk of crosslighting among the individual display lamps 112, resulting in a clearer display effect.

[0070] Among them, after the anti-light crosstalk film 15 is applied to the display bracket 14, it can also be welded to the display outer cover 12 by laser welding, but the connection method between the two is not limited to this.

[0071] The installation sequence of the display component 1 provided in this application is as follows: first, the display cover 12 and the light guide 13 are pre-positioned and connected together; then, the mating surface 1331 of the light guide 13 is fixed on the external mounting 2; then, the anti-light crosstalk film 15 is applied to the display bracket 14; then, the display bracket is connected to the display cover 12; and then the display panel 11 is installed on the mating surface 134 of the light guide; finally, the display back cover is snapped onto the display panel 11 from the rear and connected to the connecting part 135 of the light guide 13.

[0072] This application provides a household appliance, including a cabinet and a door. A display component 1 is installed on the cabinet wall and / or door. Thus, the display component 1 can clearly display the operating status and related information of the household appliance to the user.

[0073] For example, household appliances include refrigerators and dishwashers, but are not limited to these. When the display component 1 is installed on a refrigerator, it can be used to display information such as temperature, humidity, and food shelf life in each storage compartment of the refrigerator.

[0074] It is understood that the enclosure walls and / or doors of the enclosure are the external installations 2 described above in this document.

[0075] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
